A brief history of a flight controller – From MultiWii to Betaflight and beyond
I will tell you the history of probably the most successful family of Open Source flight controllers: MultiWii that continues its life today as Betaflight, EmuFlight, and INAV. Other families like OpenPilot were not that successful and practically died. On the other hand, the history of ArduPilot is not that interesting and we can leave…

INAV on rovers, boats, crawlers, tanks and other ground vehicles
What can INAV do? Well…. it can fly your multirotor drone and a fixed-wing airplane. And it can do it pretty nicely! Unfortunately, that is all it can do. Now, at least. Every year or so, I’m building an RC airboat and always wanted to build a rover based on some kind of an RC…

INAV and DJI HD FPV system – there is a light at the end of the tunnel
When DJI did not decide to add INAV and Ardupilot to the list of the supported flight controller for the HD FPV system, some people were, at least, disappointed. Long story short: DJI OSD works only with Betaflight. Period. Until today, DJI avoids the answer to the question if INAV and Ardupilot will be supported.…

Drone and RC airplane motors – everything you wanted to know but you were afraid to ask!

DJI FPV System & INAV – current situation
When DJI released updated firmware for their DJI FPV system with improved OSD, Betaflight users started cheering. The move to add OSD with elements like GPS position, the artificial horizon, etc is kind of puzzling.
